2.A step up transformer used in an automobile has a potential difference across the primary of 2200 V and a potential difference across the secondary of 25 V. What is the ratio of the number of turns of wire on the primary to the number of turns on the secondary?

Respuesta :

Answer:In a DC circuit, the power consumed is simply the product of the DC voltage times the DC current, given in watts.for AC circuits with reactive components we have to calculate the consumed power differently.

a 1/4 watt resistor or a 20 watt amplifier.
